00:00:01,920 --> 00:00:06,600
Speaker 1: Welcome to brain Stuff production of I Heart Radio. Hey

2
00:00:06,680 --> 00:00:09,280
Speaker 1: brain Stuff, I'm Lauren vogel Bomb. In today's episode is

3
00:00:09,280 --> 00:00:12,680
Speaker 1: another classic from the archives. In this one, we return

4
00:00:12,880 --> 00:00:16,520
Speaker 1: to a favorite subject of mine, cephalopods, to talk about

5
00:00:16,600 --> 00:00:21,400
Speaker 1: the not actually very scary vampire squid, which is neither

6
00:00:21,440 --> 00:00:26,599
Speaker 1: a squid nor a vampire that we know of. Hey

7
00:00:26,680 --> 00:00:30,480
Speaker 1: brain Stuff, Lauren vogel Bomb. Here, the ocean is mysterious,

8
00:00:30,760 --> 00:00:34,920
Speaker 1: arguably even more mysterious than space. But unlike space, the

9
00:00:34,960 --> 00:00:38,320
Speaker 1: ocean is teeming with a stupendous array of living things.

10
00:00:38,840 --> 00:00:41,960
Speaker 1: We haven't described even a fraction of these organisms, but

11
00:00:42,159 --> 00:00:46,640
Speaker 1: luckily we are familiar with the vampire squid. The vampire

12
00:00:46,680 --> 00:00:50,640
Speaker 1: squid Latin name vampira tooth, this infer analis isn't actually

13
00:00:50,680 --> 00:00:54,520
Speaker 1: a squid, and it definitely isn't a vampire squid from hell,

14
00:00:54,800 --> 00:00:58,280
Speaker 1: which is what that scientific name translates to. It is

15
00:00:58,320 --> 00:01:02,440
Speaker 1: a cephalopod like octopuses, squids, and cuttlefish, but the vampire

16
00:01:02,480 --> 00:01:05,960
Speaker 1: squid has a taxonomic order all to itself, and that's

17
00:01:06,000 --> 00:01:09,959
Speaker 1: because it shares traits with both squids and octopuses, not

18
00:01:10,080 --> 00:01:12,759
Speaker 1: because it's a blood sucking undead creature of the night,

19
00:01:13,280 --> 00:01:15,880
Speaker 1: although it is blood red in color and does have

20
00:01:15,959 --> 00:01:18,480
Speaker 1: a dark webbing between its arms that looks a little

21
00:01:18,480 --> 00:01:21,720
Speaker 1: bit like a cape, and where it lives it's always

22
00:01:21,760 --> 00:01:26,760
Speaker 1: pretty dark. The ocean, like the atmosphere, has strata. Vampire

23
00:01:26,840 --> 00:01:29,880
Speaker 1: squid live in the mesopelagic zone of the open ocean,

24
00:01:30,040 --> 00:01:33,120
Speaker 1: which starts where the sunny productive epopolagic zone of the

25
00:01:33,120 --> 00:01:36,520
Speaker 1: surface ends. This is down at around six hundred and

26
00:01:36,520 --> 00:01:39,759
Speaker 1: sixty feet that's two hundred meters, where that surface zone

27
00:01:39,800 --> 00:01:42,760
Speaker 1: gives way to the dim, deep twilight zone of the

28
00:01:42,840 --> 00:01:46,880
Speaker 1: mesopelagic which extends to around thirteen thousand feet or one

29
00:01:46,880 --> 00:01:51,200
Speaker 1: thousand meters below the surface. Like many other mesopolagic animals,

30
00:01:51,400 --> 00:01:54,559
Speaker 1: vampire squid dyne on bits of dead plant and animal

31
00:01:54,600 --> 00:01:58,480
Speaker 1: matter that filter down from above. Though these crimson be

32
00:01:58,640 --> 00:02:03,040
Speaker 1: caped misfits look rettening with their dark spiny underbellies, they're

33
00:02:03,080 --> 00:02:06,680
Speaker 1: not hunters and have very few defenses. Their self defense

34
00:02:06,720 --> 00:02:10,320
Speaker 1: options are to turn themselves into a squishy, black spiny ball,

35
00:02:10,440 --> 00:02:13,880
Speaker 1: like a particularly dirty pair of socks, or to spray

36
00:02:14,040 --> 00:02:17,600
Speaker 1: junk at their enemy. The cephalopods living in shallower water

37
00:02:17,680 --> 00:02:21,120
Speaker 1: protect themselves with jets of dark ink, but since vampire

38
00:02:21,160 --> 00:02:24,080
Speaker 1: squid already live in the dark. They squirt out a colorless,

39
00:02:24,200 --> 00:02:29,680
Speaker 1: bioluminescent fluid to confuse potential predators. Vampire squid also have

40
00:02:29,800 --> 00:02:33,240
Speaker 1: little lights at the end of their eight long sectionless arms.

41
00:02:33,600 --> 00:02:36,680
Speaker 1: Nobody's completely sure what they're for, but they might use

42
00:02:36,720 --> 00:02:39,200
Speaker 1: them to communicate with other vampire squid that they meet,

43
00:02:39,720 --> 00:02:41,959
Speaker 1: and what we do know for certain is that they're

44
00:02:41,960 --> 00:02:46,240
Speaker 1: not using them to hypnotize anybody and suck their blood probably.

45
00:02:51,639 --> 00:02:54,760
